2017 JEEP WRANGLER air conditioning

•Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and possibly
a collision. Driving with your foot resting or riding on
the brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible brake
damage. You would not have your full braking capacity
in an emergency.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
whenever the vehicle is serviced, or immediately if the brake
system warning light is on. If necessary, add fluid to bring
level to the full mark on the side of the reservoir of the brake
master cylinder. Be sure to clean the top of the master
cylinder area before removing cap. With disc brakes, fluid
level can be expected to fall as the brake pads wear. Brake
fluid level should be checked when pads are replaced. If the
brake fluid is abnormally low, check system for leaks.
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.
WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical Speci-
fications” for further information. Using the wrong
type of brake fluid can severely damage your brake
system and/or impair its performance. The proper type
of brake fluid for your vehicle is also identified on the
original factory installed hydraulic master cylinder
reservoir.

400 SERVICING AND MAINTENANCE

•Disconnect the negative (-) terminal from the battery
post and be sure that the battery is fully charged. During
storage check battery charge quarterly.
• If you do not disconnect the battery from the electrical
system, check the battery charge every thirty days, also
we recommend you use storage mode for more infor-
mation refer to (“Instrument Cluster Display Menu
Items” in “Getting To Know Your Instrument Panel”).
• Clean and protect the painted parts by applying protec-
tive waxes.
• Clean and protect polished metal parts by applying
protective waxes.
• Apply talcum powder to the front and rear wiper blades
and leave raised from the glass.
• Cover the vehicle with an appropriate cover taking care
not to damage the painted surface by dragging across
dirty surfaces. Do not use plastic sheeting which will not
allow the evaporation of moisture present on the surface
of the vehicle.
• Inflate the tires at a pressure of +7.25 psi (+0.5 bar)
higher than recommended on the tire placard and check
it periodically. •
Do not drain the engine cooling system.
• Whenever you leave the vehicle is stationary for two
weeks or more, run idle the engine for approximately
five minutes, with the air conditioning system on and
high fan speed. This will ensure a proper lubrication of
the system, thus minimizing the possibility of damage to
the compressor when the vehicle is put back into opera-
tion.
CAUTION!
Before removal of the positive and negative terminals
to the battery, wait at least a minute with ignition
switch in the OFF position and close the driver ’s door.
When reconnecting the positive and negative terminals
to the battery be sure the ignition switch is in the OFF
position and the driver ’s door is closed.
BODYWORK
Protection From Atmospheric Agents
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice and those that are sprayed on
trees and road surfaces during other seasons are highly

NOTE:Take care to speak into the Voice Interface System
as calmly and normally as possible. The ability of the Voice
Interface System to recognize user voice commands may be
negatively affected by rapid speaking or a raised voice
level.
WARNING!
Any voice commanded system should be used only in
safe driving conditions following all applicable laws.
Your attention should be focused on safely operating
the vehicle. Failure to do so may result in a collision
causing serious injury or death.
When you push the Voice Command
button, you will
hear a beep. The beep is your signal to give a command.
NOTE: If you do not say a command within a few seconds,
the system will present you with a list of options.
If you would like to interrupt the system while it lists
options, push the Voice Command
button, listen for
the beep, and say your command.
Pushing the Voice Commandbutton while the system
is speaking is known as “barging in.” The system will be
interrupted, and after the beep, you can add or change
commands. This will become helpful once you start to
learn the options.
NOTE: At any time, you can say the words “Cancel,”
“Help” or “Main Menu.”
These commands are universal and can be used from any
menu. All other commands can be used depending upon
the active application.
When using this system, you should speak clearly and at a
normal speaking volume.
The system will best recognize your speech if the windows
are closed, and the heater/air conditioning blower is set to
low.
At any point, if the system does not recognize one of your
commands, you will be prompted to repeat it.
To hear the first available Menu, push the Voice Command
button and say “Help” or “Main Menu.”
